Lead (300 mum) and cadmium (18 mum) inhibit pod fresh weight in soybeans (Glycine max L.) by 35%. Eighteen micromolar cadmium caused a 30% decline in nitrogenase activity by day 52 (the day on which maximum activity was measured) and a 71% inhibition by day 59. The heavy metals depressed photosynthetic rates; when photosynthesis was depressed by 60%, as measured on the day of peak photosynthesi...

Root-knot nematode, Meloidogyne incognita, is one of the main problems in vegetable-growing regions, decreasing yield quality and quantity worldwide. Root-knot nematode management tactics mostly involve chemical control which is a threat to the environment, consequences to human health. Biological control of nematodes is considered to be one of the best alternatives to the chemical control. In ...

effect of automobile pollution on the productivity of crocus sativus was studied for one year time period (october 2005-april 2006). the parameters which were analyzed viz total chlorophyll, carotenoids, leaf area, plant height, corm size, corm weight, corm yield, biomass, flower production, and length of stigma and style, showed a remarkable decrease as compared to control. total chlorophyll ,...

The growth of medicinal plants and biosynthesis of secondary metabolites is influenced by plant growth regulators. In this study we investigated influence offour levels (0, 500, 1000, and 1500 mg l-1) of2-chloroethyltrimethylammonium chloride (Cycocel), a plant growth retardant, on growth parameters and some biochemical parameters of cannabis plants. Cycocel only at 500 mg l-1 decreased shoot l...

introduction legumes are the most important source of vegetable protein supply. mungbean (vigna radiate (l.) wilczek) produces seeds contain 22-25 percent protein and high nutritional value for human and also is a major source of protein in most modern societies. rapid seed germination and emergency, is an important factor determining the ultimate yield of the plant. salinity is the most import...

in order to investigate the effects of piriformospora indica and trichoderma tomentosum fungi on basil (ocimum basilicum l.) growth under copper nitrate levels, a pot experiment in factorial arrangement with three replicates was done during 2012. treatments were four levels of copper nitrate (0, 100, 200 and 300 mg kg-1 of soil) and four levels of fungal coexistence (non-inoculation control, in...

The effects of sugar concentration and strength of basal medium were studied to produce plants from somatic embryos in Asparagus of®cinalis L. There was a signi®cant difference among concentrations of sugar but not among kinds of sugar tested in the present experiment in growth of shoots and roots. When the sucrose concentrations were 10, 30, or 50 g lÿ1, the fresh weight of shoots were 31.5, 1...
